Technical Field

The invention relates to the field of medical instruments, in particular to an intelligent hemostatic forceps.

Technical Field

Intelligent hemostats are often required in clinical procedures to prevent excessive blood loss from patients. The current common intelligent hemostatic forceps are hemostatic forceps, such as elbow hemostatic forceps, straight-head hemostatic forceps, oval forceps and the like of local blood vessels. The traditional management mode of the hemostatic forceps as a medical instrument relies on a non-automatic system based on paper documents or paper labels for recording and tracking, and asset management is completely implemented manually, so that the efficiency is low, and the number and the scale of the managed hemostatic forceps are small. With the popularization of computer application, data information managed by medical instrument warehouses of a plurality of hospitals is managed by a computer data system at present, but the data is collected and statistically organized in a mode of firstly recording paper and then manually inputting the paper into a computer. The management of hospital ward medical instruments still stays at present in that clinical medical personnel must check the used and idle medical instruments in a ward before going off work every day, and the main mode of checking is that the clinical medical personnel find each medical instrument and check the medical instrument with a medical equipment list table one by one to complete checking, and fill related records on a medical instrument record book. The traditional data entry method is low in speed and accuracy, and the paper label is easily polluted by the environment. Therefore, the requirement of increasingly refined management of various medical instruments cannot be met, and the operating efficiency of the medical instrument management department in the hospital is influenced.

Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings and the detailed description.

The first embodiment is as follows:

a first embodiment of the invention is shown in figure 1. The intelligent hemostatic forceps of this embodiment includes: the clamp comprises a clamp 1, a clamp rod 2, a handle 3, a handle fixing clamp tooth 4 and an electronic tag 5.

One end of the clamp rod 2 is connected with the handle 3, and the other end of the clamp rod 2 is welded with the clamp 1. Handle fixed clamp teeth 4 are welded on the opposite sides of the handle 3 respectively, and the handle fixed clamp teeth 4 are meshed with each other in a matching mode. Preferably, jaw 1 also includes jaw teeth on its occlusal surface. The clamping teeth make the clamped pliers not easy to slip off.

As shown in fig. 2, a rectangular through hole 6 for accommodating the electronic tag 5 and the protective resin 7 is formed in the clincher lever 2. The through direction of the rectangular through hole 6 is parallel to the horizontal plane defined by the opened forceps rod 2 of the hemostatic forceps. The electronic tag 5 is arranged in the middle area of the rectangular through hole 6 in the length direction and is wrapped by the protective resin 7.

The resin 7 for protection may employ a commonly used thermoplastic resin or thermosetting resin. The surface of the protective resin 7 is flush with the surface of the clamp rod 2, so that the smooth surface of the clamp rod 2 can be kept, the electronic tag is convenient to clean, and the electronic tag can be protected from being corroded by body fluids such as oil stain, water, blood and the like.

As shown in fig. 3 to 4, the electronic tag 5 includes a first radiation unit 51, a second radiation unit 52, an RFID chip 53, and a substrate 59. The first and second

radiating elements

51, 51 extend in a direction away from the RFID chip 53. The RFID chip 53 connects the first radiation element 51 and the second radiation element 52 together. The second radiation unit further includes a first slit 521, a second slit 522, a third slit 523, and a fourth slit 524. The first slit 521, the second slit 522, the third slit 523, and the fourth slit 524 are provided in this order on the upper surface of the electronic tag 5 in a direction away from the RFID chip 53. The connection point of the RFID chip 53 and the first and second

radiating elements

51 and 52 can move in the direction perpendicular to the length direction of the electronic tag 5, so as to adjust the operating frequency of the electronic tag 5.

According to an aspect of the present embodiment, the first slit 521, the second slit 522, the third slit 523, and the fourth slit 524 are disposed in parallel. The first slit 521 and the third slit 523 are located on the same side of the second radiating element 52. The second slit 522 and the fourth slit 524 are located at the same side of the second radiation element 52. The number of slots may also be adjusted according to the actual requirements of the tuning.

As shown in fig. 4 to 5, the first radiating element 51 extends to the side of the electronic tag 5 in a direction away from the RFID chip 53, and is formed with a first connection portion 57, and the first connection portion 57 includes a first forked electrode 571, a second forked electrode 573, and a third forked electrode 575. A fourth forked electrode 572 is provided between the first forked electrode 571 and the second forked electrode 573; a fifth forked electrode 574 is disposed between second forked electrode 573 and third forked electrode 575. The first to fifth forked electrodes are coupled to form a tuning capacitor for tuning the resonance frequency of the electronic tag 5.

As shown in fig. 6, the fourth forked electrode 572 and the fifth forked electrode 574 extend toward the bottom surface of the electronic tag 5, and form the first ground electrode 510. The first ground electrode 510 is coupled to the inner surface of the rectangular through-hole 6 to form a ground.

The length of the rectangular through hole 6 is set to be 1.3 to 3 times the length of the electronic tag 5. The first radiation unit 51 and the second radiation unit 52 of the electronic tag 5 are coupled to the upper inner surface of the rectangular through hole 6, using the caliber of the rectangular through hole 6 as a radiation aperture. The placement state of the hemostatic forceps after use can be divided into a furled state or an opened state. Since the radiation aperture of the rectangular through hole 6 is located at the side, when the hemostat of the present invention is in the folded state, the radiation aperture at the inner side is affected by the coupling of the other forceps rod, and the effect is most serious at the area closer to the RFID chip 53, and the reading distance is reduced seriously or even unreadable.

In order to obtain a stable reading distance, the present embodiment provides the isolation trace 58 on one side of the electronic tag. The isolation trace 58 is disposed in an inverted zigzag shape, one end of the isolation trace is connected to the second radiation unit 52, and the other end of the isolation trace extends to the bottom surface of the electronic tag 5 to form a second ground electrode 511. Preferably, the length of the isolation trace 58 is 40% -60% of the length of the electronic tag 5. The second ground electrode 511 is coupled with the inner surface of the rectangular through-hole 6 to form a ground. Meanwhile, the isolation trace 58 is coupled to the ground through the second ground electrode 511, and the trace length can be adjusted to tune the resonant frequency of the electronic tag while achieving isolation. After the isolation trace 58 is provided, even in a collapsed state, since the coupling current generated by the proximity of the clamp lever is introduced to the ground by the isolation trace 58, the reading distance of the electronic tag 5 can be maintained.

The radiating elements and electrodes of the electronic label 5 may be made of commonly used conductive materials, such as gold, silver, copper, or aluminum foils. It is also possible to use conductive ink disposed on the substrate by screen printing.

The operating frequency band of the electronic tag 5 may be selected from the microwave frequency band, preferably from the UHF frequency band. The electromagnetic wave can transmit the resin 7 to transmit the information stored in the RFID chip 53 of the electronic tag 5. The RFID chip 53 has unique ID information stored therein, which can be read by a reader for asset management of the hemostat. Under the UHF frequency band, the stable reading distance of the intelligent hemostatic forceps is about 1.5m, which is obtained by adopting a reader-writer, and the requirement of asset management is met.

The first embodiment is as follows:

fig. 7 shows a second embodiment of the present invention. In comparison with the first embodiment, a reactive element 54 is also connected in parallel in the vicinity of the RFID chip 53, and the remaining features are the same as those of the first embodiment. The reactive element 54 may be one of a capacitor, an inductor, a parallel capacitor-inductor loop, a series capacitor-inductor loop, or a combination thereof. The reactive element 54 is used to further tune the resonant frequency of the electronic tag and to increase the Q-value of the equivalent resonant tank of the electronic tag with the limited physical size of the clamp bar, thus helping to reduce the physical size of the electronic tag 5.

The above description is only a specific implementation of the embodiments of the present application, but the scope of the embodiments of the present application is not limited thereto, and any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the embodiments of the present application, and all the changes or substitutions should be covered by the scope of the embodiments of the present application.
